(Cover) - EN Showbiz - Adrian Grenier says his Entourage character has "changed his DNA".

The American actor is best known for his lead role as Vincent Chase in the HBO original series Entourage.

The series follows the lives of a group of male friends as they navigate their way through modern-day Hollywood.

Adrian has appeared in all eight seasons of the hit comedy show, with the final season premiering at the end of this week.

The 35-year-old star says the role of Vincent has changed the way he thinks and acts in his every day existence.

"Vince has changed my DNA. I think there's always going to be a little Vince with me at all times," he revealed in an interview with Parade.com. "Entourage really has and will continue to define an era."

Adrian has compared his final day of shooting the series to his "last day of school". The curly-haired hunk says he and his castmates, Kevin Connolly, Kevin Dillon, and Jerry Ferrara, were acting like excited kids on the last day, much to the frustration of the show's director, David Nutter.

"It was very touching. Everyone was so sweet. It actually felt like the last day of school. It was hard to keep people focussed. It was funny because the grown men on set were acting like children. Poor David Nutter was trying to get everyone's attention and get people to finish a scene, but when the end of school is near, it's hard to really get people to do anything," he laughed.
